What is required to get Jimp supporting synchronus image loading/creating? #917

Open Lukibus opened 4 years ago

Lukibus commented 4 years ago

I would like to be able to load an image from a file (though any source would be best) and know when it was available for manipulation in a synchronous way. To know when individual manipulations have completed. My application would like to load a number of images sequentially (validating input) and then once all are validating, start processing them though separate/different/combined sequences.

Calling Jimp.load(, <WITH SOMETHING INDICATING DON'T USE PROMISES>) to return an object that can be manipulated and cloned.

Tried finding a library that doesn't require some tortuous combinations of Promises that ultimately don't work for just simply loading an image file and knowing when it has been loaded and is manipulatable.

I have similar question, but specific to buffers - there's really no reason why Jimp.load(buffer) should be async - there's no IO involved and the reading from buffer is synchronous in nature. Could there be extra API to load buffer synchronously?

As a workaround, the await command will wait until the Promise resolves, so then the code might look like what you want.

let jimpImage = await jimp.read(image);
// do other things
